Build on the strength of engineeredlumber.

Take a closer look at the advantagesoffered by GP engineered lumber:

Strength Georgia-Pacific engineered lumber ismanufactured to take advantage ofthe natural strengths found in wood.GP combines high-grade wood fiberwith specifically formulated resins to

produce virtually defect-freeengineered lumber. Thismanufacturing processenables GP engineeredlumber to resist shrinking,twisting and warping. As aresult, engineered lumber is

more consistent and has more load-carrying capacity and spanning abilitythan regular sawn lumber.

Easy installation Every piece is consistently true to size.Even though its extremely strong, GP engineered lumber is lightweightand easy to cut. Plus, wiring andplumbing pass easily through the web of Wood I Beam joists for moreclearance and higher ceilings.

Environmentally soundEngineered lumber makes moreefficient use of trees because it is madeusing smaller, computer-evaluatedlumber and plywood veneers.Engineered lumber requires between 40 to 50% less wood fiber than theequivalent conventional lumber.

Engineered Lumber is an important part of every flooring system that is sturdy enough

to support heavy furniture like pool tables, pianos or china cabinets.

Todays home designs call for advancedbuilding materials like Georgia-Pacificengineered lumber. The strength ofengineered lumber makes it the rightchoice for floor and roof systems, aswell as beams and headers.

Residential building trends,including large open spaces and highceilings, create a demand for productsthat provide higher strength andgreater stability over longer spans.Georgia-Pacific Wood I Beam joistsand other engineered lumber productsoutperform conventional lumber inthese applications, helping to ensurea solid floor system and maintainstructural integrity.

Engineered lumber helps eliminatethe need for supporting posts inbasements, garages and bonus rooms.Since most pipes, duct and wires canpass through the web of Wood I Beamjoists, engineered lumber makes itpossible for you to maximize ceilingheights, even in basements.

When home designs feature wallsof windows, grand front entrances,and even wider doorways from roomto room, engineered lumber productslike GP Lam LVL headers provide thestrength and support required tohandle the heavy loads.

Lightweight and cost effective, WI andGPI Series Wood I Beam joists are thebuilders choice for residential floor androof systems. A wide selection of sizesand flange choices make it easy to specifythe materials that are right for the homesyou build, whether youre buildingproduction homes or custom plans.

Each joist features an enhanced OSBweb with high-grade solid sawn lumberor GP Lam LVL flanges. The widerflanges offered by the 40, 60, 65 and 80series joists provide broader gluing andnailing surfaces for floor and roofsheathing, helping to save time andmoney for builders. Occupants enjoy thebenefits of firm, level floors and smooth,flat ceilings.

More stable floorsWhen used as part of a flooring system,Wood I Beam joists can help floors stayquiet over time, reducing bothersome and costly callbacks. Conventionallumber can shrink, twist and warp as themoisture found naturally in the woodevaporates. Floors can bow, nails pullaway from the joists, and the floordecking slides up and down against thenails, creating annoying squeaks.

In contrast, Wood I Beam joists aremore stable by design. The wide flangehelps reduce vibration, creating a firmerfeeling floor.

NOTES:1. These span charts are based on uniform loads, as noted above; live load deflection is limited

to L/480 for better performance. Floor performance is greatly influenced by the stiffness of thefloor joists. Experience has shown that joists designed to the code minimum live load deflection(L/360) will result in a floor which may not meet the expectations of some end users. BlueLinxstrongly recommends floor spans for Wood I Beam joists in accordance with those givenabove, which are based on L/480 live load deflection. (One-third stiffer than required by code.)

2. Spans are clear distances between supports, and are based on composite action with glued-nailed APA Rated Sheathing or Sturd-I-Floor of minimum thickness 19 329 (40/20 or 20 oc) forjoist spacing of 19.29 or less, or 23 329 (48/24 or 24 oc) for a joist spacing of 249. Adhesive must

meet APA AFG-01 or ASTM D3498. Apply a continuous line of glue (about 149 diameter) to topflange of joists. All surfaces must be clean and dry. If sheathing is nailed only (not recommend-ed), reduce spans by 129.

3. Minimum end bearing length is 1 34 .99 Minimum intermediate bearing length is 312 99.4. For multiple-span joists: End spans must be at least 40% of the adjacent span. Spans shown

above cover a broad range of applications. It may be possible to exceed these spans by analyzing a specific application with GP FASTBeam selection software.

5. For loading other than that shown above, refer to Uniform Load Tables, use FASTBeam soft-ware, or contact BlueLinx Engineered Lumber Technical Services.

6. Not all products are available at all distribution centers; contact BlueLinx for availability.

The ultimate goal in the design of a floor or roof system is the end users safety and satisfac-tion. Although joists used at spans indicated in this guide meet or exceed minimum codecriteria and will safely support the loads imposed on them, judgement must be used to ade-quately meet user expectation levels. These expectations may vary from one user to another. The specifier should consider the meaning of a given deflection limit in terms of allowable

deflection and the effects this could have on the system. For example, L/360 (span/360) for a308 span is 19 of deflection. L/240 would be 112,9 and L/180 would be 29 of deflection.Consideration might also be given to cases in which a joist with a long span parallels ashort span or a foundation end wall. For example, a 308 span with up to 19 of allowable liveload deflection could be adjacent to an end wall with no deflection, causing a noticeabledifference in floor levels under full design load.

A stiffer floor will result from using a live load deflection limit of L/480 versus the codeminimum L/360. A roof system with less total load deflection than the code required L/180may be achieved by using a criterion of L/240.

In addition to more stringent deflection limits, several other factors may improve overallfloor performance. Reducing joist spacing and/or increasing the subfloor thickness will

lessen deflection between adjacent joists and increase load sharing. For increased floorstiffness, BlueLinx recommends gluing the subfloor to the joists before nailing or screwingrather than nailing alone. For additional stiffness, glue tongue and groove joints. Surfacesmust be clean and dry before gluing.

As with any construction, it is essential to follow proper installation procedures. Joistsmust be plumb and anchored securely to supports before system sheathing is attached.Supports for multiple span joists must be level. To minimize settlement when using hangers,joists should be firmly seated in the hanger bottoms. Leave a 1169 gap between joist end and header.

Vibrations may occur in floor systems with very little dead load, as in large empty rooms.A ceiling attached to the bottom of the joists will generally dampen vibration as will interiorpartition walls running perpendicular to the joists. If a ceiling will not be attached to thebottom of the joists, vibration can be minimized by nailing a continuous 2 x 4 perpendicularto the bottom of the joists at midspan running from end wall to end wall. Where future finishing of the ceiling is likely, x-bridging or Wood I Beam blocking panels may be used in place of the 2 x 4.

Depth 91/29 117/89 14 9 16 9Weight (plf) 3.0 3.7 4.4 5.0

Thickness 11/89 Length 128

CapacitiesVertical Load:

Rim or starter joist = 4850 plf.Horizontal load (lateral seismic or wind):

200 plf using a load duration factor of 160%1/29 lag or through bolt attaching ledger to rim board:

350 lbs. lateral load per bolt

Lateral loads for nails in wide face of rim board: Design per 1997 NDS using Douglas Fir-Larch values

Connection Requirements To joist: Face-nail rim board to each joist with two (2) 8d nails, one

each into top and bottom flange.

To plate: Toe-nail rim board to wall plate with 8d nails at 69 oc or 16dnails at 129 oc. See note I, page 19 for information regardingfasteners and preservative treated wood.

Subfloor: Attach floor sheathing to rim board per building code orstructural panel manufacturers specifications (closest on-center nail spacing is 69). For shear transfer (lateral seismicor wind) of up to 200 PLF, use 8d at 69 oc.

To rim: Face-nail rim boards together at corners with three (3) 8d nails.

Ledger: To attach a ledger use 12 9 through bolts with nuts andwashers or 12 9 lag screws (minimum length of 49) withwashers. Maintain 29 edge distances on ledger andrim board. For lag screws, drill 5169 lead holes in rim boardand 129 holes in ledger. Caulk holes with high quality caulkingimmediately before inserting the bolts or lag screws.Caution: The lag screw should be inserted in a lead hole byturning with a wrench, not by driving with a hammer. Over-torquing can significantly reduce the lateral resistance ofthe lag screw and should therefore be avoided. See note I,page 19 for information regarding fasteners and preservativetreated wood.

Constructed according toconnection requirements below.

Refer to details F5 and F6 for additional information.

Approved ApplicationsFiberStrong rim board has been tested and approved as a rim board and starter joist by APA-EWS. FiberStrongrim board is not recommended as a structural joist, rafter, header or ledger. For such applications, considerWood I Beam joists or GP Lam LVL or contact BlueLinx. GP Lam LVL may be substituted for FiberStrong rimboard in all rim board and rim joist applications shown in this product guide.

General Notes, Allowable Uniform LoadsFloor and Roof1. Table values are based on clear distance between supports and may be

used for simple or multiple spans. End spans of multiple span joists must beat least 40% of adjacent span.

2. Uniform loads shown below cover a broad range of applications. It may bepossible to exceed these loads by analyzing a specific application using GP FASTBeam software. For cases with cantilevers or point loads, useFASTBeam software or contact BlueLinx.

3. Both live and total loads must be checked live load against the Live row and total load against the Total row. When no value is shown in the Live row, total load will govern.

4. Verify that the deflection criteria herein are accepted by local codes and authorities.

5. Provide lateral support at bearing points and continuous lateral supportalong the compression flange of each joist.

6. Minimum end bearing length is 134 9. Minimum intermediate bearing length is 3 12 9.7. For double joists, double the table values and connect joists per detail F11.8. For proper installation procedures, refer to appropriate sections in

this publication.

NOTES:1. Refer to General Notes above.2. Table does not include additional

stiffness from composite action withglue-nailed or nailed decking.

3. L/480 live load deflection is recom-mended (See System Performancenarrative.) For L/360 (minimum codedeflection) multiply L/480 value times1.33.

4. Total load deflection is limited to L/240.

NOTES:1. Capacity is for the stated duration of load 100% floor loading 115% roof snow loading. Connector capacity depends on the model selected, quantity and size of nails used, and the size

and type of fastener support. Douglas Fir-Larch or Southern Pine web filler material has been assumed for all I-joist series and depths except for all WI 80 depths where S-P-F has beenused. Higher capacities may be available based on different header materials; please refer to appropriate reference/design guide from the connector manufacturer for expanded designinformation. Some connector/header/fastener combinations may not meet maximum joist reaction capacities and a qualified engineer should be consulted. VPA and TMP connectors arebased on S-P-F wood plates. Clinch nails across grain when possible.

2. Top mount hanger capacities shown are based on the same series and depth of Wood I Beam joists carried. To achieve design capacity shown, use 10d nails for single 134 9 thick GPLam LVL beams and 16d nails for double 134 9 thick (3 129) GP LVL, Douglas Fir-Larch or Southern Pine glulam beams. Refer to detail F12.

3. Hangers capacities are based on the lesser value of single 134 9 thick GP Lam LVL, Douglas Fir-Larch or Southern Pine Glulam beams or the same series and depth of Wood I Beamjoists carried. Refer to detail F13 and R1.

4. Bearing stiffeners required for Wood I Beam applications. Refer to detail F13.5. Beveled bearing stiffeners are required. Refer to detail R8. Maximum slope is 12/12. A tie strap is required for all Wood I Beam applications with 169 joist depths or slopes of 7/12 and

greater. Refer to detail R1.6. TMP connectors may be used for slopes of 1/12 through 6/12. For greater slopes use TMPH series connectors with bearing stiffeners.7. Nailing key. H column indicates size of nails to connect hanger to supporting header. J column indicates nails to attach the hanger to the joist. P indicates nails to connect to plate.

Fill all nail holes as required by hanger manufacturer. 10d x 11 29 is 9 gauge x 11 29, 10d is 9 gauge x 39, 16d is 8 gauge x 3 129.NOTE: Model numbers shown are for United Steel Products Company, Inc. 1-800-328-5934 (East) & 1-800-227-0470 (West) and Simpson Strong-Tie Company, Inc. 1-800-999-5099.

Storage and Handling Wood I Beam joists and FiberStrong rim board shall not be stored

in direct contact with the ground and should be protected fromweather. Provide air circulation under covering and around stacksof materials.

Bundles should be stored level. Do not open bundles until time of installation. Use care when

handling bundles and individual components to prevent injury tohandlers or damage by forklifts or cranes.

Safety WarningHandlers and installers should use appropriate personal protectiveequipment such as gloves and goggles.

Wood I Beam joists will not support workers or other loads until properly installed and braced. To minimize risk of injury, each Wood I Beam joist shall be properly fastened as it is erected.Continuous closure and/or blocking panels must be installed andattached prior to installing floor or roof sheathing. Lateral restraint,such as an existing deck or braced end wall, must be established atthe ends of the bay. Alternatively, a temporary or permanent deck(sheathing) may be nailed to the first 4 feet of joists at the end of the bay.

Rows of temporary bracing at right angles to joists must be fastened

Do not allow workers orloads on Wood I Beam joistsuntil properly installed andbraced as outlined above.

Protect products from sun and water.Use support blocks at 10* on-centerto keep bundles out of water.

DO NOT store Wood I Beam joists flat.

DO NOT lift Wood I Beam joists

by top flange.

DO NOT lift Wood I Beam joists

in the flat orientation.

Stack building materials over mainbeams or walls only.

Stack and handle Wood I Beam joists in the upright position. Stackand handle FiberStrong rim board flatwise.

Twisting of joists, or applying loads to the joist when flat can damage the joist.

Damaged products should not be used.

with a minimum of two 8d nails (10d box nails if net thickness of bracingexceeds 19) to the upper surface of each parallel joist and the establishedlateral restraint. Bracing should be 1x4 minimum and at least 8* longwith on-center spacing not to exceed 108. Ends of adjoining bracingshould lap over at least two joists. Stack building materials over mainbeams or walls only.

The following can result in serious accidents: improper storage orinstallation, failure to follow applicable building codes, failure to followproper load tables, failure to use acceptable hole sizes and locations,or failure to use bearing stiffeners when required. Installation notesmust be followed carefully.



A. Engineered lumber must not be installed in direct contact withconcrete or masonry construction and shall be used in covered,dry use conditions only, where the in-service moisture contentdoes not exceed 16%.

B. Except for cutting to length and birdsmouth cuts, top and bottomflanges of Wood I Beam joists shall not be cut, drilled or notched.

C. Concentrated loads shall only be applied to the upper surface ofthe top flange, not suspended from the bottom flange. ContactBlueLinx for exceptions.

D. When nailing sheathing to top flange, follow sheathing manu-facturers nailing recommendations, but maintain spacing in theranges shown below:

Sheathing Nail Spacing RequirementsGPI 20 GPI 40, WI 40, WI 60,

Nail Size GPI 65 WI 80Min. Max. Min. Max. Min. Max.

NOTES:

1. If more than one row of nails is required, rows must be offset by atleast 1 29 ( 349 for WI joists) and staggered.

2. 14 gauge staples may be substituted for 8d nails if staples penetratethe joist flange at least 19.

3. Do not use nails larger than those shown above when attachingsheathing to flanges of Wood I Beam joists.

Example: When using 8d common nails and GPI 20 series joists, spaceno closer (min.) than 39 o.c. and no farther (max.) than 169 o.c.

E. End bearing length must be at least 1349. Intermediate bearings of multiple span joists shall be at least 3129.

Installation NotesF. Wood I Beam joists must be supported on walls, beams, or in

hangers. They may not be supported by a non-structural ridgeboard or by toenailing into a beam.

G.Wood I Beam joists must be restrained against rotation at the endsof joists by use of rim joists, blocking panels, or cross bridging. Thetop flange of a Wood I Beam joist must be laterally supported andkept straight within 129of true alignment. Plytanium Plywood or OSBsubfloor nailed to the top flange (per Note D ) is adequate to provide lateral support.

H.When nail type is not specified in this guide, use common, box or sinker.

I. To help safeguard the structural integrity of connections withpreservative treated wood, use only hot-dipped galvanized orstainless steel fasteners, connectors and hardware.

As a minimum requirement, hot-dipped galvanized coated fas-teners should conform to ASTM Standard A153 and hot-dippedgalvanized coated connectors should conform to ASTM StandardA653 (Class G-185). In demanding applications, or in highly corro-sive environments, stainless steel fasteners and connectorsshould be utilized and may, in fact, be required by building codes.

Most commonly available electroplated galvanized fastenersdo not have a sufficient coating of zinc and are not recommended.Aluminum should not be used in direct contact with preservativetreated wood. Never mix galvanized steel with stainless steel inthe same connection.

J. Certain applications of staple-up radiant heating may cause additional deflection in I-joists with solid-sawn flanges due tounequal drying within the floor cavity. Contact BlueLinx for additional information.

K.GP Wood I Beam joists are manufactured without camber or spe-cific vertical orientation. They may be installed with the identifyingstamps on the side faces reading right side up or upside down.
